And while the company posted operating losses in both its North America and international e-commerce business, its biggest profit driver, Amazon Web Services, reported a nearly 49% increase in operating income, to $5.3 billion.

The company forecasted net sales growth of between 3% and 8% for the first quarter of 2022, a huge decline from the nearly 44% growth in sales it posted during the same period a year earlier.
